The main reason for naming it `delimit` was to be consistent with the karg `delimiter`, so `str.delimit(index, delimiter)`. You could call it `chop` I guess, but I'm just bikeshedding, so will leave it while you guys figure out the important stuff. -- Carl Smith carl.in...@gmail.com On 2 May

Sorry. I meant to be terse, but wasn't clear enough. I meant the method name. If it takes a `delimiter` karg, it would be consistent to call the operation `delimit`. On Tue, 2 May 2017 13:06 Carl Smith, wrote: > Couldn't it just be named `str.delimit`? I totally agree with

[Python-ideas] Add an option for delimiters in bytes.hex()

The bytes.hex() function is the inverse function of Bytes.fromhex(). But fromhex can process spaces (which is much more readable), while hex() provides no way to include spaces. My proposal would be to add an optional delimiter, that allows to specify a string that will be inserted between the
